Actually, yeah. Wolverine can be pretty dangerous (to those in his class) when pissed off.

One of my favourite moments was when he almost killed Marrow. All through the comic book he was patronizing her and trying to get her to see the light in becoming a full fledged X-Man, and she appeared to be turning...then out of nowhere she stabbed him in the throat. He lay there...apparently dead or unconscious, so she put him on her lap and slowly pulled back his mask, which revealed his pupilless eyes...an indication that he's ready to go feral. If you remember when Marrow was introduced, she was a badass broad, with a bad attitude, taking shit from nobody...but in this instant, she was terrified. She could see death coming, in the form of three claws. Logan pounced on her and was ready to carve her up, but Cannonball intervened and she was able to escape with her life.

I always give props to Wolverine on being a badass...in his own class. When they get into ridiculous situations (ie. vs. Hulk, Lobo, Surfer, etc) then I get turned off.

Firelord? Firelord doing anything to Surfer is hilarious, because he knows how to absorb his attacks. He's done it before.

I'd say Hulk, Thor, Surfer, Thanos, pretty much anyone who is strong in general is dangerous when they are mad.

Characters like Hulk and Damage, however, are even more dangerous because they get stronger as they get angry, and Damage gets stronger as he gets hurt as well, both of these guys can end up totaly mauling the shit out of things if given the right situation.
